    Project Ref.: Application for Contractor Prequalification, Civil Project C798
    Project Name: Design, Build, Operate & Maintain (DBO&M) contracting services for the proposed Integrated Industrial Wastewater Treatment Works (IIWWTW)


    The proposed Integrated Industrial Water Treatment Works (IIWWTW) is to be constructed approximately 2 km Southwest of Doha Industrial Area adjacent to the existing Industrial Area Sewerage Treatment Works (IASTW).  Public Works Authority (PWA) is mandated to complete the first Phase of IIWWTW (known as IIWWTW, PHASE I) by the end of year 2016 to provide 10,000m3/d treatment capacity of industrial wastewater/ trade effluent.  At the completion of IIWWTW PHASE I, the plant will provide a fully integrated solution for treating industrial wastewaters arising from light to medium categories of industrial and trade establishments located in Qatar, in conjunction with the disposal of treated sewage effluent (TSE) emanating from existing IASTW.  The proposed IIWWTW PHASE I will handle industrial wastewater tankers up to a capacity of 10,000m3/d.  These wastewaters will contain pollutant levels typically exceeding municipal discharge limits that control trade effluent disposal to public sewer network.  The design of the proposed IIWWTW will be based upon a fully-integrated solution with multi-stream treatment processes.  This concept will also allow seamless additions to the Works through its modularized design so that the plant can be expanded in future (PHASE II, PHASE III, etc.) beyond its currently proposed capacity of 10,000m3/d, when required.
